Your plant has a calcium deficiency, I noticed your only giving her 1ml at this stage she needs at 3 or 4ml of Cal-Mag instead, up that and she'll be fine.

Yep, calcium. Either too little calcium or PK nutes locking out the micros. You should know which is most likely.

Blattprobleme bei Pflanze (Wahrscheinlicher Kalziummangel?)
I have 2 plants in the tent and one of the plants is showing quite a few deficiencies. Many leaves are now yellow with brown spots. The other plant doesn't have these deficiencies, both were watered the same, etc. A few days ago, I used dolomite lime and worm castings.

Dark green leaves in meringue
Is my girl telling me that the flowering fertilizer is too nitrogen loaded? I´m using top bloom from top crop, feeding at 1.4-1.6 Ec, and since last week I started to follow the feed-water-water schedule. The NPK of this fertilizer is 4-8-8. Should I adjust the input EC?

Is my light too far away from my seedling? What should I do to correct the bend and brown spots coming in on the plant? How often should I be watering my seedling and how much? You can see these deficiencies in my uploaded photos in my profile.

Dark purple areas on leaves — genes or environment/feeding problem?
What the heck is this? Is it just purple genes or a stress/deficiency or a combination of multiple factors? I have checked three visual cannabis plant health guides, and did not find a single issue which looks like this. Maybe a combination of 2 factors, but I'm not convinced 😐
